Sinumerik Alarm 27031 Axis %1 limit value for safe velocity %2 at gear ratio %3 too large (max. %4)
%1 = Axis number
%2 = Limit value index
%3 = Number of the transmission ratio
%4 = Maximum velocity
All limit values in MD $MA_SAFE_VELO_LIMIT have to be so set, that the limit frequency of the limiting frequency of the amplitude monitoring in the measuring circuit hardware (200 kHz , from SW 4.2 300 kHz up) is not exceeded. The limit value which did not fulfil this condition is indicated as second parameter (1 for SG1, 2 for SG2, etc.). The third parameter indicates the gear stage, e.g. 1 for gear stage 1, 2 for gear stage 2, etc. The fourth parameter indicates the maximum velocity which can be entered to just maintain the limit frequency in safe operation. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready). Pulse blocking (via SGA).
– Mode group not ready.
– Channel not ready.
– NC Start disable in this channel.
– Interface signals are set.
– Alarm display.
– NC Stop on alarm.
Please inform the authorized personnel/service department. Reduce the limit value in MD $MA_SAFE_VELO_LIMIT[x], x = (2nd alarm parameter) – 1, or correct the setting of the gear factors.
Switch control OFF – ON.
